Mum house is really clean and has 3 comfortable bedrooms. We stayed here for 4 nights with total 5 people and felt enjoyable like our own house.
Mr. Bhinit was very supportive to explain in detail everything when we checked in and to drive us to the airport at 5AM, with a fair price (400BTH), when we checked out.
You should try some local restaurants near the house with really good food. I recommended the Charun Dang Restaurant (at soi 4) for Thai food and the Suansone (in the opposite side and near soi 7) for chicken rice and chinese food.
Taxi would be the most convenience transportation for a group 4 - 5 people like us to go to near by famous places such as Grand Palace, China Town, Khaosan Road from 70 - 150 THB/ each way. However, you should prepare well with the map to describe the location of the house, as Mr Bhinit suggested we should say Bangpho instead of Pracha rat sai 1.
